FWIW, Walter and I did a bunch of these for Py2.3 and had excellent
success because of a good process. Some ideas are:
* start it now (don't wait until a beta release).
* skip the packages like email which are maintained separately
* think out ways it could go wrong (operator precedence, double
backticks, escaped backticks, backticks inside strings or comments,
* do it manually (not brainlessly), then do it with automation to
compare the results.
* make sure every affected module still imports.
* run the whole unittest suite in debug mode with -u all.
* self-review the diff file.
* get a second person to do a 100% review of the diff (Walter or I would
be a good choice).
* put on an asbestos suit because the flames will come even if no
mistakes are made.
IMO, this change is much easier to get right than the ones that were
